For instance, it struck countless victims in the\r\nfake \"Chrome Font Pack Update\" campaign, encrypting victims’ files even without having to communicate over\r\nthe Internet. Minerva is releasing a proof-of-concept tool that is able to contain Spora infections by generating an\r\ninfection marker that this ransomware seeks, to determine whether it’s already running on the system.\r\nThe actual vaccination code can be found in the VaccinateSpora() method in Program.cs :\r\nprivate bool VaccinateSpora()\r\n{\r\n uint volumeSerialNumber, maxComponentLength;\r\n WinApi.FileSystemFeature fileSystemFlags;\r\n if (!WinApi.GetVolumeInformation(@\"C:\\\", null, 0, out volumeSerialNumber, out maxComponentLength, out fileSy\r\n {\r\n return false;\r\n }\r\n string mutexName = \"m\" + volumeSerialNumber;\r\n if (WinApi.CreateMutex(IntPtr.Zero, false, mutexName) == IntPtr.Zero)\r\n {\r\n return false;\r\n }\r\n return true;\r\n}\r\nSource: https://github.com/MinervaLabsResearch/SporaVaccination\r\nhttps://github.com/MinervaLabsResearch/SporaVaccination\r\nPage 1 of 1",
